IMPROVEMENT IN BALiNG-PRESSES.

Specification forming part of Letters Patent No. 215,201, dated May 13,1879; application filed March 29, 1879.

To all whom it may concern.'

Be it known that I, BERNARD W. ARNOLD, ofLitchiield, in the county OfMontgomery and State of lllinois,have invented certain new and usefulImprovements in Ealing-Presses; andl do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use Athe same, reference being hadto the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspeciiication. a

This invention consists in a cam journaled in the press-frame, andprovided on one side with a seriesof pins or shoulders arranged atvarying distances from its center of motion, and'on its other side witha cog-segment and other devices, arranged to give a to-and-fro movementto the follower and operate other parts of the press mechanism 5 and itconsists, further, in the construction of the mechanism connecting withthe cam for operating the follower and other parts of the press, all ofwhich will be herein after fully explained, and pointed out in theclaims.

In the drawings, Figure l is a horizontal section of the casing, showinga top view. Fig. 2 is a horizontal section, showing an under-side view.Fig. 3 is a vertical section, showing a side elevation of the operatingdevices of my invention, and Figs. 4 and 5 are detail views of parts ofthe same.

a is the casing, having in one end the press box al and removable dooror end board a2, and in its opposite end the side doors c3 a, andguideslots a5 a in the upperand under boards. a7 are aprons or guides tofacilitate the operation of puttin gy the hay into the press through theside doors.

b b are two rollers constructed with radial arms, and journaled in theside walls of the casing at the right hand of the press-box al, andopposite the point where the follower or piston ceases to press thebale.

b b are weighted pawls pivoted to the casing, and so arranged that theywill permit the rollers b to turn inward and toward the pressbox, butprevent a backward revolution. The bale when it has been compressed willbe held by the rollers b after the follower has been withdrawn.

c is an extensioirframe attached to the end of the casing a, to which isaffixed the operating or power mechanism of my invention.

el is the follower, to which is hinged the lever-arm or piston-rod d1and spring cl2. The head-block d3 of the follower is provided with.suitablel extensions, which project into and slide to and fro in theguide-slots cu.

The spring cl2 has one end fixed rigidly to the head-block d3, while itsopposite or free end bears upon the side of and holds the leverarm orpiston-rod d with its Outer end pressed in against the operating-cam.The piston-rod d has formed in its outer end a series of notches, d4 d5,on the side next the cam.

c is the sweep, which is drawn in `the direction of the arrows 1, Figs.l and 2, by the horse hitched to its outer end. lthas its axis journaledin the outer end of the extensionframe c, and to its axis is affixed thecam f, arranged between the timbers of said frame.

rlhe cam f has on its upper side a series of pins or shoulders, f1 f2,so arranged that they will successively engage the notches d4 d5 as itis revolved by the sweep e.

I have shown but two pins, flf2, but it will be readily seen that morethan two or only one may be employed. The notches d* d5 correspond innumber to the number of pins f1 f2. These pins may be made so that theycan be removed by being constructed with a threaded shank, which may bescrewed into a threaded hole in the cam, thus providing for a moregradual cumulative power or force as the sweep revolves.

On the under side of the cam there is formed a small segment, g, which,at the proper moment after the pressing of the bale is completed,engages a segmenth, on the pivoted arm h1, to the outer end of which isaffixed one end of the pitman h2. The opposite end of the pitman h2 isaffixed to the inner end of the lever-arm dl, near to the follower Bythe action of the-segment g on the segment h1 and arm h the follower iswithdrawn from contact with the bale into a position 4out of thev waywhen the box is being filled for the next bale.

i is a crank-lever, which has one end suitably attached to the door a3,while its other end is carried to and is formed so that it will beengaged and actuated by a projection, k, on the under side of the camj', and automatically close the said door at the moment the said camengages the lever-arm dl and begins to force the follower toward thepress-box.

When the bale is completed the end ot' the crank-lever clears theprojection k, and the door a3 Will drop open of itself unless held bytemporary props or pins on the outside.

From the description hereinbefore given, and from the drawings, theoperation of the press will be clearly understood.

When the hay is iirst put into the box it is loose, and requires littleforce to compress it; but as it becomes more compact greater force isrequired.

The pins or shoulders jl f2 and the notches d* d5 are arranged to meetthis varying force. The outer pin, f1, engages the notch d4, after whichthe pin f2, arranged nearer to the center of motion of the cam, engagesthe notch d5, and so on, according to the number of pins and notchesthat may be provided.

In this invention I employ but a single piston-rod or arm, d', formoving the follower, and the action of the latter is nearly in a directline on the bale. This arm is farthest out of direct. line when theleast power is exerted on it. As the bale becomes more compact and thepower increases the arm is drawn nearer to the direct line between thefulcrum of the cam and the center ofthe follower or bale.

The outer or free end of the lever-arm d* is held by the spring d2 atall times in proper position, so that the pins f l f2 will engage thenotches d* di' as the cam f revolves.

Material to be baled requiring but slight pressure could be pressed by amachine constructed according to my device and having but a singlenotch, d, in the arm d', and a single pin, f1. in the cam f.

Instead of the sweep e a pulley or other suitable device may be put onthe axis of the cam f, so that the press can be operated by an endlessbelt or chain connecting with a suitable horse or other power.

I claim-- 1. In a baling-press, the cam j', provided on one side with aseries of pins, f1 f2, arranged at varying distances from its center ofmotion, and provided on its opposite side with the segment g, andarranged to engage with intermediate mechanism and move the follower toand fro, substantially as set forth.

2. In a heling-press, the combination, with the head-block d3, of thefollowerd and leverarm dl, having a notch, d5, in its outer end, of thecam f, provided with a pin, f2, which engages the notch d5 in the armdl, and is operated substantially as set forth.

3. The spring d2, in combination with the head-block d, follower d, armd', provided with notches d4 d5, and cani j', provided with pins f l f2, substantially as and for the purpose set forth.

4. Thecombination, with the door a, hinged to the side oi' the casing a,andthe cam f. l1av ing the projection k on its side, oi' the connectingcrank-lever z', substantially as and for the purpose set forth.

5. The combination, with the follower d, head-block d3, arm dl, and camf, having the segment g, of the arm h1, having segment h and pitman h2,substantially as and for thc purpose set forth.

6. In a baling-press, the combination, with the follower d andhead-block d3, the single hinged arm or shaft d', having notches d4 d5on its free end held by a spring, d2, the door a3, hinged to the casinga, and the crank-lever t', of the cam f, provided on its upper side witha series of pins, f f 2, arranged at varying distances from the centerof motion, and provided on its under side with the segment g andprojection k, pivoted arm h1, having segment h and ptnian h2, allarranged tooperate substantially as and for the purposes set forth.

In testimony that I claim the `foregoing as my own I affix my signaturein presence of two witnesses.

BERNARD W. ARNOLD.
